i just installed my koni yellows and ground controls like last week. after i put them on, i found that instead of having a stiffer ride, my car was alot more bouncy. i tried to put my koni's on the firmest setting, but the car bounces like crazy. is the only way to correct this problem is to purchase a new set of stiffer springs?

and what stiffness are your current springs?

 

What was the visual condition of the Koni yellows? Without more info, I would assume they are not dampening properly. Perhaps a weak or blown shock (shot in the dark)?

Stiffer springs will make it bounce more. If it is indeed bouncing, you want more shock rebound, or less spring. If its just you not being used to the increased stiffness, then you'll just have to trake some time to adjust.

When I installed my GCs, I didn't cut the bumpstops, and it sits on them at ride height. I think between the springs (400/400) and the bumpstops, it might be more than the Konis can dampen, because even at full still, it bounces a little. Did you correctly cut your bumpstops, or are you too low and hitting even the cut bumpstops?

 

nah i didn't cut my bumpstops. maybe i should do that. i think i only had bumpstops on the front struts...is that right?

You should have bumpstops on the rear struts as well.

 

how much do i trim them?

 

It sounds like a combination of regularly hitting your bump stops wich will make it quite harsh and also being over damped with too much rebound. Soften the shocks up to about 1 turn from soft and recheck your ride height and bump stop contact point. What are the spring rates?

 

also how low are you? how low you are can affect what spring rate you should run to prevent bottoming out.

 

i'm completely slammed. damn man...i'm such a noob with suspension. becuase it was so bouncy, i put it even more closer to stiff. its like almost completely on firm. becuase i'm slammed, how much should i trim the bumpstops?

 

instead of cutting the bumpstop, raise the car.

 

awww is that the only way. if so then damn. i really like the way it looks right now.

 

^ That's slammed?

 

with those rims + tires. yeah thats slammed.

 

so what should i do? raise it a little?

 

Yes raise it up a bit to get is off the bump stops and soften the rebound damping down to between 1/2 to 1 turn from soft. The car will be much more livable. Trimming the bump stops a bit would be a good ideas and it should have bump stops on all four corners.
